The Endless Stair CM8 D&D 1st edition 1e AD&D Dungeons Dragons adventure module

Description

This is the D&D adventure module CM8, The Endless Stair, a rare adventure for the original D&D ruleset written by Ed Greenwood, the guy who created the world of the Forgotten Realms.
This copy of the module is in Excellent condition.  I don't know its full history, but it looks like it could be New Mint.  It has practically no shelf wear,  and still looks fresh.  It has lived in a sealed plastic sleeve for a long time.  I skimmed the contents, and didn't find any marks, outlining, or stains.  The staples on the main booklet are unrusted.  It's a beautiful copy.
Shipping:
Generally my go-to shipping method for any printed material too heavy to travel 1st Class is Media Mail, but I'm willing to switch to Priority if you like.  I am happy to combine shipping on multiple purchases; I don't try to make my profits out of shipping.  If, however, you buy a bunch of minis and a bunch of printed stuff, I may ship them in two packages if that saves money, or else use a Priority Mail Flat Rate box if that makes more sense.  Short version: I try to give you the best deal on shipping that I can!
